I found in the fecelift models, CD spec and below was disappointing.
CDX onwards is where the toys all kicked in. Of course, you'll pay a bit more for an Elite over a CDX, but you should get leather (based on standard factory spec), rear blind (removed from 52plate onwards), sat nav and GID (CID if lucky) screen, heated rear seats, automatic occupancy front seat detection (for passenger air bag) and sportier alloys.
That said, if you get a CDX with leather, do you really use the other toys much anyway.
I have found the sat nav a bit lacking in places and prefer Tomtoms. Shame you can't build in a Tomtom so that it's theft protected.
As for maunal/auto... I drive 3.2s in both formats day to day and prefer the auto hands down.
I find the manual gearbox sloppy, uninspiring but very little improvement in accelaration or top speed. Yes, the auto is thirstier, but using the kickdown 3,2,1 with sports mode correctly, I can select the correct gear to maintain high revs when taking corners, roundabouts, etc through the entire speed range.
I'm willing to bet my mortgage that you will not be able to source a 51 plate onwards in manual with elite specification with below 80k mileage. You may find MV6 equivalent, but as Theboy stated, in facelifts, the spec is very lack lustre.
Good luck in your hunting.....
